Weather in July
Temperature
During the warmest month, July, temperatures average a high of 84.2°F (29°C) and a low of 67.3°F (19.6°C).Heat index
July's heat index is estimated at a sweltering 95°F (35°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
